I/O specification

Detailed specification of the Universal HIL Connect I/O stage.

Analog outputs

Analog output-type signals are driven via HIL Analog Outputs, with a maximum of 32 channels. To increase the flexibility of the device, HIL analog outputs are:
  1. Buffered and routed to the output (AO1-32)
  2. Amplified to high voltage, and routed to output connectors (AO1-16)
  3. Converted from voltage to current, and routed to output connectors (AO17-AO32)

Analog inputs

The analog input stage is an opamp buffer stage, with all 16 channels routed through the Universal HIL Connect.

Digital outputs

The digital output stage is implemented via push-pull gate drivers. The driving signal comes from HIL DO1..32 channels. Essentially, the whole section is behaving as a level shifter, converting 5V logic signals from HIL to the industry-standard 24V logic.

Digital inputs

Digital input stage is implemented with all logic levels in mind, thus enabling connection of any controller digital output signal to any of the 32 HIL DI channels.
